Apparatus for automatically supplying and selectively reproducing a plurality of cassettes and for avoiding the reproducing of degraded signals

摘要

In an apparatus for automatically supplying and selectively reproducing a plurality of cassettes, the error rate for each cassette and for each reproduction is automatically generated and stored in a separate area of a memory and, when the error rate exceeds a threshold rate, the deteriorating cassettes are automatically dubbed onto blank cassettes to ensure that deterioration of each tape or other record medium never exceeds a predetermined amount. In addition, the operator may independently cause any cassette to be dubbed when he deems the image produced therefrom to be too highly degraded regardless of the error rate of the signal recorded therein.
